Ambry Genetics

Dec 28, 2023

The c.59C>G (p.A20G) alteration is located in exon 1 (coding exon 1) of the ADAD2 gene. This alteration results from a C to G substitution at nucleotide position 59, causing the alanine (A) at amino acid position 20 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
